Zsnventor 62 0/ 4. A a/ssefl M WW 2/ Gttomegs Patented June 3, 1952 UNITED STATES OFFICE 2,599,415 PUTTY REMOVING DEVICE Cecil B. Russell; Tulsa; Gkla'. Application: October 15, 1949, Serial No. 121,588 4 Claims. (01. 90-12)" This invention relates to a device for removing putty or other caulking compounds from ride along the sash rails for supporting the cutters in operative position relatively to the glazing compound to be removed and without injury to the sash or glass retained therein; and to provide a putty-removing device with an adjustable. head for carrying the guides for movement coaxially of the cutters.

In accomplishing these and other objects of the invention, I have providedi'mproved structure, the preferred form .ofwhich. isillustrated inthe accompanying drawings wherein:

Referring more in detail to the drawings:

I designates a puttyor caulking: compound removing device constructed in accordance with the present invention and which includes aecasing. 2

containing a suitable electrical motorthat is supplied with an' electrical currentthr'ou'gh conductors 3 connected with a plug that is adapted to" be engaged in any convenient. wall socket; At.- tached to the motor casing} isaa gear casing 5 enclosing a gear fi mountedioni shaft 1 of the motor and which meshes withxdriven gears? 8- and 9 that are mounted on. stub. shafts HI and: H which are suitably journaled in the gear casing. The shafts l and II have ends l3 and "14 extending through openings l and I6 that are provided in the end wall ll of the gear casing 5, as best shown in Figs. 1 and 4. The shafts l0 and! ll have bores !8 extending inwardly from the ends I 3' and M of the shafts to receive shanks I9 of cutters 20' and El- The shanks l9 may have shouldered ends 22 adapted to engage shoulders 23' inthe inner ends of the bores It to provide a driving connection between the shafts and cutters. The shanks of the cutters are suitably re tained in the bores by spring clips 24 that are carried" by the shafts I'Uand II and which are adapted to yieldingl'y engage within annular groves 25 that are formed in the shanks I0 and I I, as illustrated in Fig. 4'. A

The cutters project from the end wall I! and have spiral cutting edges 26 terminating in flat ends ZTlocated' in planes extending at right angles tothe axis of the cutters and which are adapted to rotate in close proximity with a glass pane 28 contained within a window sash 29 while the spiral cutting. edges 2'6. rotate in contact with putty used in'glazing. the glass within rabbet grooves 30 in the rails of the sash. Such grooves are usually ofang-ular shape and have one side 3|" for seating the glass and the other side 32 backingthe putty applied within the angle formed'by the adjacent face of the glass and the side 32 as in conventional practice.

In order to support the device with the cutters in proper relation to the glass and rails of the sash,fla guide supporting head 33 is mounted for adjustablesupport on the casing 5, as now to be described? The head-33'includes a plate portion st having sub'stantially fiat inner and outer faces Hand 36', diametrically, opposed arcuate ends 31 and'38', and parallel sides 39and 40, as best shown tained in .fixedposition therein by thumb screws 49 and 50, having threaded shanks 51- threadedl-y engagedin'threaded openings 52 of the brackets to bear against the arms, as shown in'Figs. 2 and 3.

In order to pass the plate portion of the head over the cutters, the plate portion is provided with laterally spaced bearings 53 in which the cutters rotate, as shown in Fig. 3.

Mounted on the outer face 36 of the plate portion of the head and extending between the cutters is a guide block 54 having-a guide face 54 located in a plane tangent to circumferential faces of the cutters as shown in Fig, 3, and which is located at right angles to the outer face 36 of the plate portion of the head so as to engage the face 32 of the rabbet grooves of the sash rails and to support spiral cutting edges of the cutters in position to cut out the putty, but to retain them out of cutting engagement with the sash rails, as later described.

The block 54 may be backed by a similar block 55 that is secured to the plate portion of the head by fastening devices 56 and which is of longer length to overlap the ends of the guide block and form a protection for the cutters. The plate portion of the head is adapted to move along the outer face 51 of the sash rails so as to retain the end faces 27 of the cutters in close proximity to the glass and to facilitate movement therealong. The plate portion has spaced substantially rectangularly shaped openings 58 and 59 which are shown in Fig. 2 as being in substantial registry with the cutters for mounting guide rollers 60 and 6!. The guide rollers are adapted to rotate on pins 62 that are extended through openings 63 formed in the plate portion at substantially right angles to the face 54 of the guide block 54 whereby the rollers are adapted to rotate on the face of the sash, while the face 54' of the guide block is moved along the face 32 of the rabbet grooves.

To facilitate support of the device in the hands of the operator, the motor casing tube may be provided with a handle 64 by which the device is supported in straightway position with respect to the side faces 32 of the rabbet grooves when the guide block 54 is moved therealong.

While the gears 6, 8 and 9 may be of suitable diameter to give the proper speed with respect to the motor, the speed of the motor may be varied by means of a rheostat 65, as represented by the switch lever positioned on the outer side of the motor casing, as shown in Figs. 1 and 3.

In using the device, the head 33 is adjusted to project the cutters 20 and 2| in accordance with the depth of the grooves in a sash. This is effected by loosening the thumb screws 49 and 50 and sliding the arms 4| and 42 within the brackets 45 and 46 until the cutters project from the face 36, a distance equal to the depth of the putty groove. Then when the rollers 60 and GI roll upon the face 51, the end faces of the cutters just clear the glass 28. The device is held in the hand by means of the handle 64 and the guide block 54 is placed against the putty. With the motor in operation, the cutters eat into the putty until the face 54' of the guide block engages the face 32 of the putty groove. The device is then moved along the rails of the sash in either direction so that the spiral cutting edges of the cutters remove the putty along the length of the sash rails and mullions. The cutters also remove the glaziers points and leave the grooves clean and free of the old putty. The glass may then be reglazed with new putty, as in the usual process of glazing.

From the foregoing, it is obvious that I have provided a device which is adapted to quickly and cleanly remove old and broken putty from window sash without danger of breaking the glass. It is also obvibus that the cutters are adapted to any depth of putty groove within the capacities thereof merely by adjusting the guide head.

What I claim and desire to secure by Letters Patent is:

1. A device of the character described including a motor casing, a motor in the casing, spaced cutters rotatble in the casing, a driving connection between the motor and cutters, a guide head adjustably supported on the motor casing to control the cutting depth of the cutters, and a guide block on the guide head intermediate the cutters to cooperate with said head in supporting the cutters within the putty groove of a window sash.
